Question

1. Why is the time difference between each meridian of longitude 4 minutes? Explain.
2. Distinguish between Equator and Prime Meridian.
pls try to give answers little longer as 6 marks​

Answer 1

Explanation:

The Earth rotates 360° of longitude in 24 hours, which means that for 1-degree rotation of longitude, the Earth takes 4 minutes. As the Earth rotates, every meridian on it faces the Sun at least once. ... The time difference is thus 6 hours between the two.

Answer 2

Answer:

1. There are 360 meridians which represent 360 degrees of a full rotation of the earth - relative to the sun. Since the period of the earth's rotation takes 24 hours, each meridian represents 24/360 hours = 24*60/360 minutes = 4 minutes.

To establish time zones, Earth's rotation rate of 360 degrees of longitude per day was divided by 24 hours. The result shows that Earth turns 15 degrees of longitude per hour. Adopting time zones that are exactly 15 degrees wide would result in 24 equally spaced time zones around the world.

The earth has 360 imaginary lines called longitude or meridians running vertically between the poles. ... So the time difference between each longitude in 4 mins.

Each degree of longitude is sub-divided into 60 minutes, each of which is divided into 60 seconds.

2. The Equator separates the Northern and Southern Hemispheres. The Equator is at 0° latitude. The Prime Meridian separates the Eastern and Western Hemispheres. The Prime Meridian runs through Greenwich, England and is at 0° longitude.

Zero degrees latitude is the line designating the Equator and divides the Earth into two equal hemispheres (north and south). Zero degrees longitude is an imaginary line known as the Prime Meridian.

Which is longer equator or prime meridian?

The earth is commonly modeled as a sphere flattened 0.336% along its axis. This makes the equator 0.16% longer than a meridian (a great circle passing through the two poles.

How are the equator and the prime meridian used on maps?

To separate Earth's four hemispheres. The prime meridian and the Equator, on their own, can only be used for the separation of the four hemispheres on the Earth. The Equator is dividing the Earth in South Hemisphere and North Hemisphere.
